LONDON (Hollywood Reporter) - "Doctor Who" fans will be forced to go for almost two years without a series fix from the Tardis-travelling Timelord, because actor David Tennant will take time off to do stagework, the BBC said Monday
The fourth season of the latest iteration of the sci-fi action drama will air in the spring of 2008, but season five will be delayed until 2010, BBC director of fiction Jane Tranter said Monday.
The show is one of the public broadcaster's biggest success stories in recent years and has proved an international hit.
The BBC will air three one-off specials during 2009 and a Christmas special in 2008.
Tennant will work with the Royal Shakespeare Company in Stratford Upon Avon on projects thought to include a lengthy run of "Hamlet."
